If a team end up drawing 2-2 but in the 50th minutes a goal was unfairly chalked off due to a ref cock-uo.
The common logic is….”if the ref hadn’t blundered we‘d have won 3-2, so the ref has cost us 2 points”.
However this is a flawed logic because goals change games…some teams start sitting back losing momentum…losing teams push forward threatening goals but are then open to the counter attack…some teams gain confidence and go on to score more goals and the timing of a goal can be so important.
My point is……we’ll never know what effect the ghost goal really had….if that goal has been allowed…it might have given Villa a big kick up the backside and they come back to win. So weirdly that disallowed goal might have cost Villa 2 points and gained us an extra point,
The only scenario that I agree that a mistake directly effects the result of a match is if a ghost goal occurs in the last 2 or 3 minutes of a match.
